INITIATING APPARATUS Original Filed April 15 1924 Patented Apr. 21, 1931 UNITED: STATES MILO HERRIGK SPAULDING, F IBOZEMAN, MONTANA INITIATING ArrAaA'rUs iOriginal application filed April 15, 1924, Serial No. 706,729. Divided and this application filed March. 11,1927. Serial No. 174,541.

My invention relates to new and useful improvements in initiating apparatus and the present application is a division of my application filed April 15, 1924, Serial No.

The principal object of the invention resides in the provision of a lodge room arch constructed so that a keystone or similar emblem may be raised into position at the top or over the arch and supported at such position.

Another object of the invention resides in the provision of means whereby the keystone may be detachably connected to the hoisting cable or rope.

With the above and other objects in view, which will appear as the description proceeds, my invention consists in the novel details of construction and arrangement of parts described in the following specification and illustrated in the accompanying drawings, and while I have illustrated and described the preferred embodiments of the invention, as they now appear to me it will be understood that such changes may be made as will fall within the scope of the appended claims.

In the drawings:

F ig. 1 is a front elevation of an arch showing the keystone in position while being hoisted.

Fig. 2 is a side elevation of the arch and its associated parts. I Fig. 3 is a top plan view of the keystone. Fig. 4 is an elevation of a modified form of device for attaching a keystone to its sup-' porting cable.

Fig. 5 is a combined side elevation and top plan of another modified form of the invention.

an arch to which a support 2 is adapted to be connected by means of the brackets 3. The bracket 3 is connected to the back of the arch and the lower end of the support 2 is received therein. The support 2 has, at the top, a horizontally extending arm 4 which reaches over the top of the arch and carries a pulley 5. A rope or cablefl6 passes over the pulley and to one end of this rope or cable is connected a keystone 7 which is adapted to be raised or lowered upon manipulation of the rope or cable. The keystone is preferably provided in its upper surface withthe slot 8 adapted to receive the lower end of a rod 9, said rod 9 having the enlargement 10 at its lower end and the eye 11 at its upper end. The rope or cable 6 willbe secured to the eye 11. Secured to the front. face of the arch, adjacent the top, is the frame .12, of keystone shape, which is adapted to receive the keystone, when hoisted, and support the same at the top of the arch.

In Fig. 4 of the drawings I have shown a slightly modified form of the device for connecting the keystone 7 to the rope or cable 5. This consists of a vacuum cup 13 which is adapted to be connected to the rope or cable by means of the hooked wire or rod 14, the vacuum cup engaging the upper surface of the keystone.

In Fig. 5 of the drawlngs I have illustrated a still further modified form of means for connecting the keystoneto. the rope or cable; this means being in the form of a quarter turn screw 15. The threaded portion of the quarter turn screw 15 is received in an interiorly threaded plug 16 which is inserted in the keystone. V

In Fig. 6 I have shown another form of connecting means between the keystone and the rope or cable. In this form of connection a plug 17 is inserted in the top of the keystone and has a bayonet slot 18 to receive the projections 19 carried by the rod or link 20 having the eye 21 at the upper end to receive the rope or cable 6. I

In-Fig. 8 I have illustrated still another modified form of means for attaching the keystone to the rope or cable. In'this form of the invention I provide a tong-like con- 100 struction consisting of the arms 22 pivotally connected together at 23 and having their upper ends connected by means of the short chain 24. The lower end of the rope or cable 6 is connected to the chain 24 intermediate the end thereof and when the rope or cable 6 is drawn upwardly the ends of the arms 22 will be forced into tight engagement with the sides of the keystone as shown in the drawings.

ith the arch in position the keystone will be connected to the rope or cable 6 in any of the ways illustrated in the drawings and the keystone will be raised by pulling upon the rope or cable. In hoisting the keystone will be preferably raised to a point slightly above the frame 12 and then will be lowered so as to be seated in the frame and supported thereby.

From the above it will be seen that I have provided'a novel form of means for hoisting a keystone and novel means whereby the keystone may be detachably connected to the rope or cable.

Having fully described my invention what I claim as new and desire to secure by Let ters Patent is:

1. An initiating apparatus including an arch having a connecting upper portion, a support carried by the arch and having a horizontal portion extending over the top thereof, a keystone, and means carried by the support and engageable with the keystone for raising and lowering the keystone relative to the arch.

2. An initiating apparatus including an arch having a connecting upper portion, a removable support carried by the arch and having a horizontal portion extending over the top thereof, a keystone, and means carried by the support and engageable with the keystone for raising and lowering the keystone relative to the arch.

3. An initiating apparatus including an arch having a connecting upper portion, a frame carried by the connecting portion of the arch, a support carried by the arch and having the horizontal portion extending over the top thereof, a keystone, and means carried by the support and engageable with the keystone for raising and lowering the keystone relative to the arch and positioning the same in the frame or removing the same therefrom.

4. An initiating apparatus including an arch having a connecting upper portion, a frame carried by the connecting upper portion of the arch, a. keystone, and means adapted to be detachably connected to the keystone for raising and lowering the same relative to the arch and positioning the same i bracket secured to the arch, a support removably connected to the arch by means of the bracket and having a horizontal portion extending over the top of the arch, a keystone, and means connected to the horizontal portion of the support and engageable with the keystone for raising and lowering the keystone relative to the arch.

6. An initiating apparatus including an arch having a connecting upper portion, a bracket secured to the arch, a support removably connected to the arch by means of the bracket and having a horizontal portion extending over the top of the arch, a keystone, and means connected to the horizontal portion of the support and adapted to be detachably connected to the keystone for raising and lowering the keystone relative to the arch.

In testimony whereof I hereunto aiiix my signature.
